All Glacial and Periglacial Processes (World)

This group collects the 33 Physical Processes subcategory members that the atlas already places under its own Glacial and Periglacial Processes subcategory, the whole real-world population the atlas covers there. It is a single flat group, not split further by region or country, because Glacial and Periglacial Processes stays well under ruling 926's own hundred-member threshold for a further split (the largest sibling geography subdiscipline subcategory in this pass, still under 100 members). It sits directly under the Glacial and Periglacial Processes subcategory (in-subcategory) and under the atlas's own Groups category (in-category), giving a reader a direct browse path from either the Glacial and Periglacial Processes subcategory page or the Groups index. SourceId is intentionally NULL on both the group-to-subcategory edge and every member's own in-group edge below: the underlying classification already lives on each member's own live Glacial and Periglacial Processes subcategory placement, a fact already recorded and sourced when the member itself was minted; filing it under this atlas's own browse structure is an organizational fact about the atlas, not a new claim about the world, the same convention w-groups-build-0922 and w-groups-group-geography3-0923 already established for this identical shape of write.
